RADIATOR FOR 'HEATING-IU'RNACES.

The schedule referred to in these Letters Patent and making part of the same.

I, QnARLss HAnKzxsoN, 'of Philadelphia, county of Philadelphia, State oflPennsylvania, haveinvcnted an Improved Radiatorfor Heating-Furnaces, of which the following is a specification;

Nature and Object of thclnventz'on. My invention consists of an improved radiator, constructed in the manner fully described hereafter, so

that dust and soot can find-no lodgmcnt in the upper portion of the-same, but will fallto the bottom, whence it can be readily removed.

yMy invention further consists of certain improvements in the construction of the radiator, hereafter explained.

, Dcscrip tionof the Accompanying Drawing.

3 Figure- -1 is a plan view of my improved radiator, showing the.fnrnacewithin which it is contained, in dotted lines; i

Figure 2, avert-ical section ofthe same Figure 3, a sectional plan on the line 1-2, fig. 2; and

, General Description.

On reference to fig. 1-- I *A represents the outer brick casing of a heating furnace;

jB, thefire-chamber .or furnace proper, arranged within the sameandsurrounded by the hot-air space (1; and

' D, my improved radiator, arranged within the caslug-at the back of the fire-chamber, and communicating with'the latter through a pipe, to.

.The radiatoroccupies, in. the present instance, the

"entire width of the furnace, and consists of an oblong box, F, which I prefer to makeof cast-iron, and of a number of vertical sheet-metal tubes or drums, H, attached to the top of and communicating with the in teridr of the said box,.andeach surmounted by a cap, 1), which can, if desired, be madedctachable, as shown in fig. 2.

The interior of the box F is divided into a number ofcompartments, We" a, &c., by. vertical partitions g, which also extend upward into each of' the drums H, dividing the latter into equal compartments, which 7 communicatewith each other ata point above the partitions.

The products of combustion, therefore, which enter the first compartment of the radiator through the pipe a, must pass upward through the first drum at one side of the partitions g and descend at the 0ppo-' site side, in order to enter the second compartment e, and must likewise rise to the top of each'of the succeeding drums, as indicated by the arrows in fig. 2, before they can pass ofi' through the outlet-flue J,

. which, in the present instance, extends upward from a branch, K, of the radiator, through oneof the side walls of the furnace; g

By thus compelling the heated products of combustion to pass ina circuitous course through the radiator, instead of escaping at once to the outlet-flue, an

extended heating-snifitce is presented to the air with in the chamber 0, which is consequently rapidly heated and brought to a fit condition to be conducted to the rooms above.

In radiators of this class as heretofore constructed,

the drums, instead of being divided by simple partitions, have been made in pairs, connected at the top I by means of elbows, the latter afiording'a lodgment for dust and soot, which rapidly accumulates and interfereswith the draught, and is exceedingly difficult to remove. l

By employing single drums with simple vertical" partitions, however, quite as effectual a circulation of the heated gases is obtained, while no lodgmcnt for dust and soot is afforded, the latter falling to the bottom of the box l fro1n which it can be readily re- .moved from time to time onremoving'caps 11 covering openings in the side of the box,access being had to these caps through a man-hole, j, formed in the rear wall of the furnace.

Instead of the caps 'i for covering the openings in the side of the box, sliding doors i, such as repre-' sented in fig. 4, may be employed.

In order to enable the dust, 850., which accumulates in the compartment 6 of the radiator to he removed,.the branch K, which communicates with the said compartment, is provided with a detachable cap, m. c i

Thiseap m is also perforated with a row of holes, m, so that it may be drawn outward to a slight extent, as shown in fig'. 2, when it is desired to check the draught of the furnace.

Although but three drums, H, are shown in the drawing, it will be evident that this number can be increased or diminished without departing from my a invention. 1

C Mints.

1; The arrangement within the box F and drums H of the vertical scribed.

22. The arrangement in respect to the drums and partitions g, substantially as decrnnpartments ot' the box F, of the covered openings in the side of the said box.

7 3. The branch K communicating with one of the compartments of the radiator, arranged to project through one of the side walls of the furnace, and having at its outer end a detachable perforated cap, m,

substantially as setforth.

In testimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses. p
